Hello,
We have encountered this possible bug today. We just played Seal after a few months of hiatus and noticed that in two separate computers and separate logins, the item menu is stuck on the lower left hand corner.
We are also having issues dragging the items we want to the quick menu. Again, this is not just happening to me but another friend as well. Hopefully this issue will be resolved soon!
Merry Christmas and Happy New year everyone!
I will be posting a photo of it shortly if you need clarification. We are both playing in the Arus server, btw.
